Question

Aarushi was driving a car with uniform speed of 60 km/h. Draw distance-time graph. From the graph, find the distance travelled by Aarushi on
(i) 2 1/2 Hours
(ii) 1/2 Hour

Answer 1

Answer:

(i) The distance cover with 60 km/h speed in 2.5 hours is 150 km

(ii) The distance cover with 60 km/h speed in 0.5 hours is 30 km

Step-by-step explanation:

Given as :

The speed of car driven by Aarushi = 60 km/h

( i ) The time period = 2 hours 30 min

i.e  T = 2.5 hours

Let The distance cover with 60 km/h speed = $D_1$ km

∵ Distance = Speed × Time

i.e $D_1$ = 60 km/h × 2.5 h

∴ $D_1$ = 150 km

So, The distance cover with 60 km/h speed in 2.5 hours = 150 km

( i i ) The time period = $\dfrac{1}{2}$  hour

i.e  t = 0.5 hour

Let The distance cover with 60 km/h speed = $D_2$ km

∵ Distance = Speed × Time

i.e $D_2$ = 60 km/h × 0.5 h

∴ $D_2$ = 30 km

So, The distance cover with 60 km/h speed in 0.5 hours = 30 km

Hence, (i) The distance cover with 60 km/h speed in 2.5 hours is 150 km

            (ii) The distance cover with 60 km/h speed in 0.5 hours is 30 km
